针对半干旱半湿润地区的流域特性和产汇流特点,比较了河北雨洪模型和新安江模型的模型原理和模型特性,以滦河支流老牛河流域为例,开展了洪水预报适用性研究。结果表明,河北雨洪模型的预报精度较高,更适用于半干旱半湿润地区的洪水预报。
According to the basin features and runoff characteristics, this paper compared the Hebei storm flood model and Xin'an- jiang model in the model principle and structure. Taking the Laoniuhe River Basin as a case, an applicability study was made. The results show that the precision of the Hebei storm flood model is higher, and is more suitable to flood forecasting for the semi-arid and semi-humid areas.
